Figure F24. Scanned core photographs of aphyric basalt from Unit IX (volcaniclastic) showing features that suggest that the large basalt clasts in this unit might be lava pillows fragments. A. Curved margin with traces of hyaloclastite attached (interval 330-U1372A-16R-1A, 117–125 cm). B. Radial trains of vesicles (interval 330-U1372A-16R-1A, 47–62 cm). C. Basalt fragment embedded in hyaloclastite matrix (interval 330-U1372A-16R-2A, 75–91 cm).
